This is 김서윤 — someone who has never existed. 김서윤 is 46 years old, lives in 안동, South Korea, at 학교길 104 (36759 안동), and works at 순항전자. The phone +821079389583 follows South Korea's real numbering rules and the inbox behind the email actually opens, yet no detail here belongs to a real person — each one is assembled on the spot from real-world naming and address patterns. Any match with a real number or address is pure coincidence. Use 김서윤 freely wherever you would rather not hand over your own details.
